Current thinking on backups ?

Hi,

What are people doing for backups ? My current process is LVM snapshot and backup from that to NFS share. But there seems to be hints around the internet that people use/abuse "doveadm backup" for backup purposes even though it seems its original intention was for transferring mailboxes between dovecot instances. Assuming its ok to "doveadm backup" to an NFS share, is it ok to use "doveadm backup" when dovecot has replication setup (replication-notify etc.)  ? Or will it interfere ? Thanks! Laura
